O Muhammad ﷺ, your people have given you so many offers, yet you've refused them all. And they have asked you for wealth from your God, and you have not given us that. So I swear by Allah, I will never believe in you until you climb up to the skies in front of me with a divine ladder, and bring down a book from Allah. Show us the angels. And even if you do so, I still won't believe in you.
Said publicly before the Nadi, the assembly of Quraysh, in the early Makkan period.
